3. Triangle ABC has angle measures as shown. (a) What is the value of x? Show your work.
(b) What is the measure of angle C? Show your work.[tex]A=3x+28 B=5x+52 C=2x-10 The are the triangle equations dor the shape the side is a b and c

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.

you can not solvr this without numbers

answer: 1.06 km per sec

step-by-step explanation:

39.6 m=63.72 km

60 min in an hour so 63.72/60=1.06
